Embedding Flutter In Your App for Fun and Profit
summary
The Games team at The New York Times embeds a Flutter module into existing iOS and Android apps, shipping the Spelling Bee prototype to production and juggling a tiny team. Integration uses either AARs deployed to an internal Maven repo or direct source dependencies, CI via Bitrise, and AndroidX only. Startup shows ~2s delay and ~40 MB per engine so performance comes from priming the Flutter Engine and caching it, and interop relies on method channels (JSON over channels) to reuse native logic while avoiding crashes on unsupported x86_32 devices.
